Fridge freezers often have two temperature control knobs—one for the fridge and one for the freezer—despite only the fridge knob controlling the thermostat. The purpose of the freezer thermostat knob is to control the airflow or damper between the fridge and freezer compartments, rather than directly regulating the freezer temperature. Here's why:
Temperature balance: The fridge and freezer compartments in a fridge freezer are connected, and air circulates between them to maintain proper temperature balance. The freezer thermostat knob helps regulate the amount of cold air that flows into the fridge compartment. By adjusting the freezer knob, you can control the temperature in the fridge section indirectly.
Minimizing frost buildup: The freezer thermostat knob also plays a role in preventing frost buildup in the freezer. When you adjust the freezer knob to a colder setting, it increases the airflow into the freezer, helping to maintain a lower temperature and reducing the chance of frost accumulation. This control helps to keep the freezer compartment at an optimal temperature for freezing and long-term storage.
Customizable settings: Having separate control knobs for the fridge and freezer allows for individual temperature preferences. Some people prefer a colder fridge or a slightly warmer freezer, depending on their specific storage needs and usage patterns. The two knobs provide the flexibility to adjust the settings according to personal preferences.
It's important to note that while the freezer thermostat knob indirectly affects the fridge temperature and helps regulate the airflow, it does not directly control the freezer temperature. The actual freezer temperature is typically controlled by a thermostat located inside the freezer compartment.
If you are experiencing temperature issues or have concerns about the performance of your fridge freezer, it is recommended to consult the manufacturer's instructions or contact their customer support for specific information related to your model.
